When i open my computer now, i was so shock because there is no sound i don't know what happen. i don't do anything changes for the sounds. i want to know how i manage my sounds because it tells me that no audio output device installed. i hope you can help me.
I have Toshiba Satellite U300. After using it for one year , i had to use the recovery DVD to re-install Vista. I got the red x on the volume control with the message: "No output device installed".
To solve this problem :
try to re-install the driver and manually point to the driver's file
If this doens't work, update the bios software, it takes 2 minutes.
this will make it work.
Hi! I just had the same thing happen to me today.... Go to your control panel, make sure it is on classic view. Click on device manager Scroll down to sound, video, and game controllers click on the plus to pull down the drop down menu right click on the driver that is there and click on uninstall. once it is uninstalled restart your computer and it will automatically reinstall itself...
hope this helps you! it did me!!!

Open the Control panel
2. Open the "Sounds and Audio Devices" icon.
3. Verify the "Place volume icon in the taskbar" checkbox is checked. If this option is not available or is grayed out, skip to the next section of this document.
4. If you were able to check this box, click ok and close out of this window and the Control Panel.
5. Double-click the sound icon in the Systray and verify that all the sound volumes are mid-way or higher.
Check Windows services. Right Click My Computer and Manage. Choose Services and Application > Services. Choose "Windows Audio" and set to Automatic and Start.
Now next you can do is
If you open control panel & click device manager the window that opens will show a list of all installed hardware. Look for anything with an exclamation mark beside it, or to do with sound. If you see anything, right click it, check it isn't Disabled then select "Properties." The next window should have some tabs along the top, the one you are looking for is "Driver," you should now see an "Update driver" button.
Check ur sound card information by doing this
Click on start menu
Click on Run
Type dxdiag, enter
Click on the sound tab
There is button of test direct sound click on this check if there is sound
Check ur registry. Check if the sound registry key is enabled or disabled. There could be an error in registry, run registry cleaner reg in out to scan for errors.
Bad News boy, Since you already checked the drivers and teh volume option. which makes it eaasy for us to identify the root cause of the problem.
So try these steps.
1. Check in sound and audio device properties in control pannel, if you have the correct audio device listed. also check if nothing is on mute in volume control.
2. if its not the correct one. i suggest remove the existing driver from add and remove program and then try reinstalling it.
3. If thats the correct one, then Check if the external speakers / head phones produce sound.
4. if yes, then everything is fine in the computer, Don not do anything as all the software is fine.
5. If no, then the internal speakers have gone bad, which is ver rare, but it may happen.
Consider replacing the internal speakers,
I am sure this will help you.
Best of Luck!

OPEN YOUR "CONTROL PANEL"...THEN OPEN "HARDWARE AND SOUND" 2. LOOK FOR AND CLICK OPEN "DEVICE MANAGER" 3. SCROLL DOWN TO '' SOUND,VIDEO AND GAME CONTROLLER'' 4. RIGHT CLICK "SOUND VIDEO AND GAME OPTION"...THEN AN OPTION WILL COME UP SAYING..."SCAN FOR HARDWARE CHANGES"...CLICK IT
You need the sound driver I assume for this laptop. If it doesnt match hardware perfectly then nothing will work.
Go to vendors site with your S/N and Model number to locate the exact sound driver.
Have you checked in control panel / sound speech / sounds & audio devices / click on "sounds" blind and see if any of the sounds can be activated by clicking the big black arrow. If greyed out then the driver is not installed.
Hi, Right click "My Computer" and go to manage. When the next screen opens go to "Device Manager" in the right hand pane you will see a list of hardware, expand "sound, video and game comtrollers". if you see a yellow exclamation mark here there is something wrong with either the driver or hardware.
First thing to do if you see a exlamation mark or not is to right click the audio controller and select uninstall.
Once that has finished click on any item in the device list and look at the top of the window, you will see a computer icom with a magnifying glass on it, Click on this.
Your computer will now search for any hardware that is not installed and re-install the audioo drivers for you.
If your computer cannot find the drivers, then you need to go to your computers manufacurer website and download the latest drivers from them and re-install.
Let me know how you get on, if it does not work we can try a couple of other things.
dianegotty: Start by clicking on this link. Find your exact model number on that page and click it. Next you will choose the operating system installed on your computer. Finally you will be taken to a "driver" download page. Download and install the software for your audio/sound device.
